BLEACHING COMPOUND FOR JUTE PAPER-STOCK, 806.

SPECIFICATION forming part of Letters Patentg No. 312,525,

dated February 17, 1885.

Application filed September 22, 1 MKSyfiuim i T0 aZZ whom it 11mg concern:

Be it known that we, PETER SoUDERs, CHEsTEE SMITH, HORACE M. ORAIGHEAD, and NoRToN SoUDERs, citizens of the United States, residing at Rieglesville, in the county of Hunterdon, and State of New Jersey, have invented certain new and useful Improvements in Bleaching Compounds for Jute Paper-Stock, 850.; and we do declare the following to be a full, clear, and exact descrip' tion of theinvention, such as will enable others skilled in the art to which it appertains to make and use the same.

his invention has relation to bleaching jute paper-stock; and it consists in the process hereinafter set forth, and pointed out in the appended claim.

In carrying out this process the jute-stock is first thoroughly washed in the usual manner. Then a composition of ten pounds of alum, four pounds of South Carolina clay, and two gallons of water is boiled and added to five hundred pounds of the stock, which is then run in the mixing-engine for fifteen minutes, after which fifty pounds of bleachingpowder are added. I11 like proportion the composition and bleaching-powder are used with larger amounts of the stock, so that one-half of the bleaching-powder used in the processes heretofore employed is saved, as it has required one hundred pounds of bleaching-powder to bleach five hundred pounds of this stock.

Resulting from this process it is designed to produce a paper of better color and greater strength, and the manufacture is cheapened and facilitated, not only by lessening the quantity of bleaching-powder, but by avoiding to a great extent the annoyance of foam and the use of coal-oil in killing the same. It also saves the wire-cloth jaeketing and the felts used on the paper-machines.

Having described this invention, what we claim, and desire to secure by Letters Patent, 1s

The process of bleaching jute paper-stock which consists in mixing with the stock acomposition of alum and clay raised to steamheat, and afterward adding a quantity of bleachingpowder, in the proportion and manner substantially as set forth.

In testimony whereof we affix our signatures in presence'of two witnesses.

. hi. PETER 2 SOUDERS.
